crocus: export GEM handle with RDWR access rights 

Without this, it is impossible to export gem handles with write access.

This was fixed the same way for
i965 (https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/10850) and
iris (https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/10851).
